At last a great speed testing app.

Tan O

Simple to use and consistent results test after test. Provides the usual metrics and many more than most other speed testing apps out there. Recognises your connection type (wired / Wi-fi), your device and your ISP.

Your settings and results are saved so you can keep track on how your ISP is performing. I think there is nothing more that I can think of that could make this app any better.
